I've used IRIS when I started but gave it up for registax and dss: It's the linux of astrophoto software, pretty unfriendly and lotsa command lines, no?
wouldn't mind giving it a try again - do you have a routine? maybe you can give me a list of commands
Yes, Iris is not especially user friendly, but that's what makes it so powerful - the user has complete control of every aspect of the image processing.
When I first looked at Iris, I gave up after a few hours for the same reason you cite. Later I found Jim Solomon's Astrophotography Cookbook on the web, and the first time I followed his steps, I succeeded in producing my best astro image up to that time. I highly recommend that you have a look at it.
Later, I developed a set of scripts to use that essentially provided some automation to the process in Jim Solomon's cookbook. The scripts are simply a listing of the various Iris commands I use, in sequential order. I made a web page describing the scripts in some detail, and including a link to download the scripts:
I recommend first using Jim Solomon's cookbook to gain some familiarity with Iris and the image processing steps, then try my scripts, or study them and make your own scripts. It's still not as easy or as fast as DSS, but in my experience the results are usually superior.
There are five separate scripts, and they break down Jim's process into five steps:
- creating the master flat image
- creating the master dark image
- calibrating the light images
- registering the calibrated images
- stacking the registered images
The result from the fifth step will need some post-processing in Photoshop, just as the result from DSS does.
The first four steps seldom if ever need tweaking. The fifth step just about always produces a decent result, at least as good as the result from DSS. Occasionally, I find it necessary to do some manual work in Iris using the intermediate images produced by the fifth script in order to tweak the result before taking it into Photoshop for final processing. My web page goes into some detail on that.
